This score crashed when i tried to save it to the cloud and i can't recover my progress

I've been working for about an hour on this score, that was already previously saved to the cloud. When hitting save, the program first displayed the "saving to cloud" progress bar for a few seconds then crashed. Upon reopening it, I wasn't prompted with the usual "recover progress" dialog box that I always get when something like this happens. When opening the score, the hour of progress i had made on it was gone, both on the online version on my score manager and on the local file. I attached it here in case there is something i can do about it, but i doubt it.
